Sep 25, 2012 Thread starter #3 jkoster Materials Sep 24, 2012 3 Do you have a source for that information? This for a piping system operating at 10,000 PSI and 250°F. Upvote 0 Downvote

Sep 25, 2012 #4 metengr Materials Oct 2, 2003 15,478 My source would be use of equivalent materials as found in ASME B&PV Code, Section II, Part D. At 250 deg F you are well below the threshold for time dependent properties. The UTS or YS will govern piping design at this service temeprature. Upvote 0 Downvote
